Y'see, people who know about this sort of thing say you're[1] talking shite. CO2 levels in the atmosphere are higher than they've been for at least 500,000 years, possibly 1,500,000 years. It seems unlikely that "in a century" a million years of natural carbon cycle will suddenly change it's mind and start sucking the stuff up. [1] I don't think it's anything personal.

Who said it would suck the stuff back up, I'm talking about what goes into our atmosphere? I agree, I think it will get worse regardless of what we do. Depending on Milankovitch's major or minor cycles either it's the 1,500,00 year one (above) or the shorter one (below) It looks like we are heading for a mini ice age in the next couple of centuries. Similar to the ones Bruegel painted in the 16c. Or the 10,000 year one: A bit more green house gas. Heat things up. Melt more arctic ice into the Labrador current. Change the salinity of the sea. Stop the Atlantic conveyer from circling the North Atlantic. Europe has an ice age. The Sahara goes green. And what ever the other things happen. > > >[1] I don't think it's anything personal.

Similar to the ones Bruegel painted in the 16c. According to wikipedia there are 23,000, 26,000, 41,000, 100,000, and 400,000 year cycles, with the 100,000 year cycle being the most (or perhaps only) one that has particular effect on climate. We are (apparently) 50,000 years away from the next ice age as predicted by the Milankovitch theory. A theory which doesn't actually fit the ice age data very well. The 'mini ice age' was not a global phenomenon, i.e. it was local cooling more akin to the recent couple of cold winters we've had where changes in the distribution of heat occur, rather than in the amount. > A bit more green house gas. > Heat things up. > Melt more arctic ice into the Labrador current. > Change the salinity of the sea. > Stop the Atlantic conveyer from circling the North Atlantic. > Europe has an ice age. > The Sahara goes green. Would take 1000-1500 years, according to people who study this sort of thing. Apparently there isn't enough ice to reduce density enough to overcome the temperature difference.
